Warnings issued when several consecutive malfunctions occur that lead to an interlocking of the AKAS@
with displayed error reports. The interlocking status can be cancelled only by a voltage reset.

over of the slow speed position monitors into slow
speed. Check the SGA line for interruptions and
check also the slow speed position monitors and
their lines.

Readjust the Hex switches onto the selected opera-

repeats itself, a repair by Fiessler Elektronik is ne-
cessary.
invalid Hex switch position

are received
Turn HEX switch into a permitted position
The transmitter is triggered although the foot pedal is
released, or a transmitter from another AKAS® fo-
cuses the receiver. This must be prevented by ade-
quate constructional measures.
unequal slow speed con-

This error happens only during the operating mode
"for connection to safety PLC" if the signals at the
SGO and the SGS are not exactly the same.
The key switch ot the front reset switch have been
activated when the foot pedal was pressed, or there
is an error within the foot pedal, or the front reset
button does not close.

internal error
If this message is displayed immediately after a vol-
tage reset, there is an EMC problem or an internal
failure of the appliance.
